I am confused about the voltage needed to charge - It appears to be a "standard" USB connecter on the one end, and that's normally 5Vdc not 15.

A standard home or car USB charger will not charge the ASUS Transformer eee pad. This cord works perfectly when connected to the wall charger that came with the tablet, which from what i've read is a higher voltage than a usual charger.

The way i understand it your correct the way the voltage changes is the charger dongle block that came with your tablet the usb cables are all the same, but the charger has the diffrent out put. I know it sounds nuts but i gave up trying to figure it out when i learned that

Charge voltage is standard USA 120V. Wall-Plug on charging unit is US Standard as well.Not sure if the unit is designed for higher voltage. Please check with Dewalt.

Do you mean the voltage output? If so, it outputs USB voltage (5 V DC at a max of 2 amps).

I'm using the USB port on the back of my cable box which is the same as a standard computer USB port. I have no idea how many volts it is.

AC Adapter may not be pushing enough voltage to charge it. I use a USB charger

The voltage on USB charger ports are 5V. That's the standard voltage for all USB ports. Thanks!

I have a USB volt-amp meter. When the Cyren is off and USB connected and charging, the USB is at 5.11V and the Cyren is drawing 580 mA. A computer USB port must source at least 500 mA. So, if you have a dedicated USB power source that supplies more than 500 mA, like 1 Amp or 2 Amp, it would charge the Cyren a little faster, but not much faster.

Well, I don't imagine it matters what you plug in PROVIDING it's a standard size USB connection. You could call the vendor.

You can hook up +5v to +12v to the VCC pin if you have an external DC power source, otherwise you need to use the USB.

This uses standard 110 volt outlet, but it's actually a USB cord so you may be able to plug it in a USB outlet to charge it.

This is 5V charger for USB devices. You can't use this to charge the laptop

Hi, I'm a little confused... If it's a tablet, doesn't it charge via USB? If it's a laptop I could understand the choice between 9 and 12 V but if it's a tablet, i'm not really sure whether 9 or 12 volts are used...

If you plug the cable into a European computer, the USB is the same. If you want to use the charger that plugs ito the wall, the you must use an adapter that converts the 220 Volts to 110 Volts. Very simple.

Is the port round or USB shaped? What is imprinted by the port? It needs to say 5v and the cord needs to be for the same mm as the 5v hole on the charger. So, if you need USB or AC on one end of your cord, you will need to have a hole (port) on the charger that is 5v and 3.5 mm in size on the end that connects to the battery charger. Amazon sent me a query for help for you since I had ordered the cord you're asking about to power my laptop fan from the laptop USB port. FYI, I googled your charger to look for the cable specs. Some were showing USB-shaped port on the charger. Some showed a round hole with 5v printed on the side. I couldn't determine the hole size without spending a lot more time, and I didn't want you to have to wait on some information, at least. Good luck!

I bought this charger in july this year in the US, i use in in the netherlands with a 230 V power outlet, it had a 110V USB charger included, so when you replace the USB charger for a local one, it works perfectly.Greeting Johan

We have bought and used two of these with no charging issues. So I'm suspecting that your voltage is different than what's required. I would contact the company. See this link:

USB only provides 5 volts which would most likely be not enough to charge your laptop. If you want to charge your laptop in a car you would be better served getting an 12V DC to 120V AC inverter with adequate wattage.
